Abstract

A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A device, comprising:
 a first electro-active lens optically aligned with a first conventional lens, the first electro-active lens comprising a first electro-active layer and a second electro-active layer, the device adapted to focus an image of an object over a range of distances. 
 
     
     
       2. The device of  claim 1 , wherein:
 said first electro-active layer is adapted to provide a cylindrical power correction. 
 
     
     
       3. The device of  claim 1 , wherein:
 said first electro-active layer is adapted to provide a spherical power correction. 
 
     
     
       4. The device of  claim 1 , wherein:
 said first electro-active layer is adapted to provide a range of optical powers. 
 
     
     
       5. The device of  claim 1 , wherein:
 a plurality of regions of said first electro-active layer is electrically interconnected via a single interconnect. 
 
     
     
       6. The device of  claim 1 , wherein:
 said first electro-active layer comprises a multi-grid electro-active structure. 
 
     
     
       7. The device of  claim 1 , wherein:
 said first electro-active layer is a high-order aberration corrector. 
 
     
     
       8. The device of  claim 1 , wherein:
 the first conventional lens is adapted to provide a spherical power correction. 
 
     
     
       9. The device of  claim 1 , wherein:
 the first conventional lens is a single fixed-focus optic. 
 
     
     
       10. The device of  claim 1 , wherein:
 the first conventional lens is a multifocal optic. 
 
     
     
       11. The device of  claim 1 , further comprising:
 a controller adapted to focus the device over the range of distances. 
 
     
     
       12. The device of  claim 1 , further comprising:
 the first conventional lens. 
 
     
     
       13. The device of  claim 1 , further comprising:
 a second conventional lens. 
 
     
     
       14. The device of  claim 1 , further comprising:
 a second electro-active lens. 
 
     
     
       15. The device of  claim 1 , further comprising:
 a Fresnel lens in optical alignment with the first electro-active layer. 
 
     
     
       16. The device of  claim 1 , further comprising:
 a diffractive optic in optical alignment with the first electro-active layer. 
 
     
     
       17. The device of  claim 1 , wherein:
 said second electro-active layer that is a high-order aberration corrector.
